My application to join the Army has been deferred until May next year due to medical grounds. I want to join the Royal Artillery as an Observation Post Assistant. I was wondering if I would still be able to arrange some familiarsation visits while ineligable to apply?

Depending on your med condition, I would strongly advise a visit to your nearest TA unit, they should be able to give you an idea what being an OPA is all about over a weekend. If your deferment if definitely for a year, then you may be able to fill in this time with the TA to get some idea of the job. Good luck!
